Demings said his agency and state wildlife officials would look into the issue of warning signs.

"There nothing in this case to indicate that there was anything extraordinary" in terms of neglect by the parents, Demings said.

Wildlife officials captured and killed five alligators after the boy was snatched.

They slit the animals open to look for traces of the boy, officials said,

Nick Wiley, head of the Florida Fish and Wildlife Conservation Commission, said it was too early to say whether one of those five might be the alligator that took the boy, Reuters reports.

"There is a good chance we already have the alligator because we focused our efforts in that proximity, in that area where this incident occurred," he said, adding that the probe would focus on results of forensic tests and bite marks on the child's body.

Wildlife officials said the attack was a rarity in a state with an alligator population estimated at 1 million.

The area near where an alligator dragged a 2-year-old boy into the water near Disney's upscale Grand Floridian Resort and Spa in Lake Buena Vista.

The child had waded no more than one or two feet into the water around nightfall Tuesday when he was taken from a small beach, authorities said.

The boy's father desperately tried to fight off the gator, suffering lacerations on a hand, but he could not save his son. Neither could a nearby lifeguard, officials said.

No other alligator attacks have been reported on the man-made lake, according to Demings.

The sheriff said the company has a wildlife management system and has "worked diligently to ensure their guests are not unduly exposed to wildlife here in this area."

The beach where the reptile grabbed the child is part of the luxury Grand Floridian resort, across the lake from Disney's Magic Kingdom theme park.

The lake stretches over about 200 acres and reaches a depth of 14 feet. It feeds into a series of canals that wind through the entire Disney property.
